GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 401,626, dated April-16, 1889.. 4 Application filed July 2, 1888, Serial No. 278,737. (No model.)

.To @ZZ whom, it may concern:

Be it known that I, HAROLD J. BELL, a citi- Zen of the United States, residing at Gloucester City, in the county of Camden and State of New Jersey, have invented new and useful Improvements in Gas-Governors, of which the following is a specification.

My invention consists in a gas-governor or gas-regulating burner having the features of construction hereinafter described and claimed.

In the annexed drawings, illustrating the invention, Figure 1 is a vertical section of a portion of a gas-regulating burner embodying my improvements. Fig. 2 is an elevation of the lower part of the regulator-shell with its tubular perforated stem. Fig. 8 is a plan of the lower part of the regulator-shell. Fig. 4 is a perspective of the regulator-valve.

The regulator-shell consists of a lower part, 1, and an upper part, 2, as shown in Eig. 1. The lower part of the shell is formed with an internally-threaded neck, 3, for attachment to a gas-fixture. Around the upper portion of this neck is formed a flange, 4, having a perforation, 5, that is plugged by a movable screw, 6, for a purpose hereinafter explained. Above the neck 3 and communicating therewith is a tubular stem, 7, having lateral perforations 8. The lower part of this stern is surrounded by a cup or annular open top chamber, .9,whichis externally screwethreaded, as shown in Fig. 2, for the engagement therewith of internal screw-threads in the upper part, 2, of the regulator-shell, as shown in Fig. 1. The stem 7 and cup 9 are integral with the iiange 4 and neck 3, and the cup or chamber 9 is elevated sufficiently above the flanged portion of the neck to form an annular gas-passage, 10, which surrounds the lower end of said stem beneath the cup. In the bottom of the cup 9, opposite the inner end of the screw 6, is a perforation, 1l, through which gas is admitted into the annular passage 10, and the perforations 5 and 11 and screw G are preferably inclined, as shown in Fig. 1, s0 that by adjusting the screw 6 inward or outward, as required, the quantity of gas admitted to the annular passage 10 can be regulated with great nicety.

It will be observed that the upper end of the tubular stem 7 is closed and provided with a contracted vertical prolongation or guide, l2, for an approximately bell-shaped float valve, 13, the lower portion of which is flared outwardly to very nearly fit the internal diameter of the cup or chamber 9, within which said valve is adapted to rise and fall, according to the varying pressure of gas within or beneath said float-valve. The float-valve 13 is provided internally with a tube, 14, which surrounds t-he tubular stem 7 and normally rests on the bottom of the cup 9 or on a shoulder, 15, which may be formed around the base of the tubular stem. In the upper portion of the tube 14, within the flaring outer portion of the valve, are openings 16 for the passage of gas. The lower end of the tube 14 is of less internal diameter than the upper portion of said tube, and the contracted portion of the tube closely embraces the tubular stem 7 and forms an annular valve, 17, for controlling the passage of gas through the perforations-or gas-openings 8 in the tubular stem. Above the contracted valve portion 17 of the tube 14 there is ample space for the passage of gas when the valve is lowered, and if the pressure of gas is excessive it will exert sufficient force within the upper portion of the tube 14 and beneath the haring or conical portion of the float 13 to cause the same to rise along the guide 12 and enable the annular valve 17 to diminish the flow of gas through the openings 8. The form of the float-valve 13, with its inner perforated tube, 14, is shown in Fig. 4. l

The upper part, 2, of the regulator-shell rests on the flanged portion of the lower shell part, 1, and this upper part, 2, as shown, supports a perforated disk, 1S, and an atmospheric-gas tube, 19, having lateral air-inlets, 20; but it is obvious that a burner of any -suitable kind may be attached to the gasregulator shell, either with or without an atmospheric-gas tube.

` The internal diameter of the upper shell part, 2, is sufficiently large to provide .a proper gas passage or passages, 21, leading from the annular gas-passage 10 upward around the cup 9 and float-valve 13 to the burner, and in IOO order that the externally-screw-threaded cup 9 of the lower shell part, 1, may be capable of affording a proper attachment 'for the upper shell part, 2, Without obstructing the HOW of gas said cup part 9 is externally cut away at one or more places, as shown at 22 in Figs. 2 and 3, the remaining outer portion of said cup being screw-threaded, as shown.

The operation of the gas-regulating devices will be readily understood by observing the course of the gas, as indicated by the arrows in Fig. 1. By means of the screw 6 the quantity of gas admitted through the opening 11 to the gas-passages 1.0 and 2l can be controlled at Will, While the pressure of the gas Will be automatically regulated by the rising and falling of the iioat-valve 13, so as to produce a steady and economical light.

In concurrent applications, Serial Nos. 278,732, 278,734-, and 273,735, of even date herewith, I have shown gas-regulators having a construction similar to that claimed herein, but each differing in certain particulars set forth in said applications.

In application Serial N o. 273,734 the governor is constructed and ar ianged for use with an ordinary gas-burner, While the construction described in the present application is intended for use Vwith atmospheric-gas burners.

Vhat I claim is- Y 1. In a gas -governor or gas regulating burner, the combination, With the regulatorshell having a tubular perforated stem closed at its upper end and provided with a'guide, of a cup or annular chamber surrounding said stem near its lower end, and a flaring or conical iioatn valve surrounding the stem above said cup and provided With an internal perforated tube to control the gas-openings in said stein, substantially as described.

2. In a gas governor or gas regulating burner, the combination of the two-part shell l and 2, having tubular perforated stem 7, cup 9, having opening 11, the adjusting-screw 6, the float-valve 13, having a perforated tube, 14, and the gas-passages 10 and 21,- substantially as described.

In testimony whereof Iafx my signature in presence of two Witnesses.
